Yeah, sounds like a silly question, but every time I look at the various specification pages for this, I get different answers.
I've just fitted a set of NGK's in my F reg 525i e34. It's got the M20 cambelt engine. The shop where I bought them gave me a gap of 0.6mm, which seems a little tight to me. Another source gave me a plug gap of 0.8mm. Another said 0.11mm.
Any of those right?
What's the proper gap, please?
Thanks.
Spark plug gap.

Last time I did it I used 0.7mm on NGKs -seemed OK!

Thanks Morat.
I'll leave them as they are for now then and see how they perform.
